As a departure from previous practice, this volume of Opuscula presents ten articles on a single theme: manuscript and print in late pre-modern Iceland, the period between the advent of print in the early sixteenth century to the establishment of the Icelandic State Broadcasting Service in the early twentieth. Throughout this period, manuscript transmission continued to exist side-by-side with print, the two media serving different, but overlapping, audiences and transmitting different, but overlapping, types of texts. The authors take their point of departure in recent developments within literary and cultural studies which focus on the artefactuality of texts and the social, historical and cultural contexts in which they are produced and consumed. The volumes title refers not only to the popular late medieval and early modern genre of exemplary and/or admonitory mirror literature -- several examples of which are discussed -- but also to the idea that both manuscripts and printed books are reflections of virtue in a broader sense.
